J. P. WHITE, OF PHILADELPHIA, PENNSYLVANIA, ASSIGNOR TO HIMSELF AND FRANCIS FOX, OF SAME PLACE.

APPARATUS FOR HEATING TIRES.

Specification of Letters Patent No. 20,767, dated. June 29, 1858.

To all whom it may concern:

Be it known that I, J OSEPH P. WHITE, of the city of Philadelphia and State of Penn sylvania, have invented a new and useful Improvement in Apparatus for Heating Tires; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawing and to the letters of reference marked thereon.

My invention consists in so combining acasing, having a lid and a revolving grating, with a fire chamber and a blowing apparatus, and in so arranging the whole, that a flame of intense heat may be forced into the casing and take a course around the same,

.thereby imparting to the tire, placed on the grating, a uniform heat throughout, and this with much less fuel, and with greater rapidity, than by the usual modes of accomplishing the same object.

In order to enable others skilled in the art to make and use my invention, I will now proceed to describe its construction and operation.

On reference to the drawing, which forms a part of this specification; Figure 1 is a ground plan of my apparatus for heating tires. Fig. 2 a sectional elevation on the line 1, 2. (Fig. 1.) Fig. 3 a sectional elevation of the casing with the revolving grate, on the line 3, 4. (Fig. 1.)

Similar letters refer to similar parts throughout the several views.

A represents the base or foundation of the apparatus, on which is supported a casing B, which contains the circular grating C, the sides of which consist of the upper and lower rings a and I), connected together by the vertical strips 0, the bottom of the grating consisting of the central bar (Z and smaller bars 6. To the top of the casing is hinged a lid E, the rim of which fits into an angular recess formed in the edge of the casing, for a purpose hereafter set forth.

To the central bar d of the grating is secured a vertical shaft D, arranged to turn.

in the bottom of the casing and in a block F, secured to the foundation A, and on this shaft is a bevel wheel G, gearing into a pinion H on the shaft I which turns in a standard F secured to the base, and on which is a wheel K, gearing into a pinion J on a shaft M, which also turns on the standard.

On the shaft M is a pulley N, around which passes the cord or strap O, which also passes around the smaller pulley P on the shaft Q of the fan blower R, which may be of any of the usual forms or constructions.

S is a firechamber, having a grating i, and an opening at the top for receiving the fuel. This fireplace communicates at f with the blast pipe of the fan blower, and at h with the interior of the casing B.

T is a pipe for conveying the products of combustion from the interior of the cas ing to any adjacent chimney. I propose to line the inside of the fireplace, as well as the inside of the casing and lid, with firebriek or other material capable of resisting the action of the heat.

The fuel being ignited in the fire chamber and the tire being deposited on the grating, the lid E is closed, the rim dipping into water or a body of fine sand deposited in the recessed edge of the casing, so as to prevent the escape of the products of combustion through any other outlet than the exit pipe T. The shaft M is then caused to revolve, when, by means of gearing already described, a rapid, rotary motion is imparted to the blower shaft, and a slow motion to the grating C.

The direction of the blast and the situation of the passage h, from the fire chamber to the casing are such, as regards the situation of the latter, that the flame, the heat of which is increased in intensity by the blast, takes the course pointed out by the arrows around the interior of the casing and makes its exit through the pipe T. The continuous rotation of the grating causes the flame to act on every portion of the tire, and, consequently, to impart to it a uniform heat throughout, and this much more rapidly, and with much less fuel, than by any of the usual modes of accomplishing the same object.

I claim anddesire to secure by Letters Patent;

The casing B with its revolving grate and lid, in combination with the fire chamber S and fan R, or other equivalent blowing apparatus, when the whole are arranged for joint operation, substantially, as and for the purpose, herein set forth.

In testimony whereof, I have signed my name to this specification before two subscribing witnesses.

JOSEPH P. WHITE.
